    The invention relates to an electric machine having a magnetically-mounted reluctance rotor and a pole-forming stator, which has at least one electric stator winding for generating an electromagnetic control flux and at least one permanent magnet for generating a permanent magnetic flux, wherein the electric machine comprises electromagnetic and permanent magnetic circuits Depending on the rotor angle, superimposed on the torque and / or radial load capacity formation at least in partial regions of the air gap.
    In order to be able to generate a bearing force for a radial magnetic bearing of its reluctance rotor in the case of a reluctance drive, it is known from the prior art (DE10062753A1) to superimpose an electromagnetic control flux in the air gap with at least two permanent magnet fluxes in order to reinforce and strengthen on one pole side a different pole side or on other pole sides to achieve a weakening of the flux density of the electromagnetic control flux. This results in the formation of a resultant force, with a force vector summed over the rotor circumference, pointing substantially in one direction, for example for controlling a radial position of the reluctance rotor relative to the stator. In order to achieve a strengthening and a weakening of the flux density, the permanent magnetic poles are arranged between electromagnetic poles, wherein both polars are assigned to the stator. The disadvantage must be operated by such a pole arrangement increased design effort to keep the magnetic losses due to increased flow loop paths low. In addition, it is necessary for the control of the magnetic storage and for

    The invention has therefore, starting from the above-described prior art, the task of improving an electric machine with a magnetically mounted reluctance rotor so that by simplified design conditions magnetic losses are reduced and / or improved torque behavior of the electric machine is possible. In addition, a simplified control of the electrical machine, in particular the magnetic bearing of the reluctance rotor should be possible.
    The invention achieves the stated object in that, when the magnetic circuits are viewed separately, at least at a rotor angle, an essential part of at least one magnetic flux is within a permanent magnet polar formation having the same polarity, within an electromagnetic polarity having the same polarity, or within one coherent and winding-free one , in particular ferromagnetic, stator sector, via the air gap and via the reluctance rotor to form a magnetic circuit.
    If the magnetic circuits (permanent magnetic and electromagnetic circuit) are viewed separately, at least at a rotor angle, a substantial portion of at least one magnetic flux within a permanent magnetic pole formation having the same polarity, within an electromagnetic pole configuration having the same polarity, or within a continuous and winding-free one , in particular ferromagnetic, stator sector, over the air gap and the reluctance rotor to a magnetic circuit, then an improved focused force direction for the magnetic bearing can be made possible in a structurally simple manner, because the magnetic circuit can be kept within narrow design limits. It is irrelevant whether the permanent-magnetic or electromagnetic circuit keeps in this limit formed by one or more poles, which is decisive for a
    As compared with the state of the art, improved magnetic bearing means that a lower flux distribution over the flux-guiding elements of the electrical machine and thus a high force-generating bearing component can be made possible by such a created boundary. Such a limitation can be created structurally simply by way of magnetic flux barriers in the stator and / or also via an arrangement of the permanent magnets on teeth of the stator, in particular on pole shoes of the stator, etc. Of course, the superimposition of the fluxes can be dependent on the angle of the reluctance rotor with respect to the stator with respect to their distribution at amplitudes and / or phase, or can be dependent on the rotor angle. The invention can therefore be distinguished not only by its constructive simplicity but also by the fact that with a comparatively low cost, an electromagnetic control flux can be generated which can serve for sufficient force generation for improved magnetic bearing of its reluctance rotor. In addition, the thus reduced magnetic paths can reduce the voltage drops, which can lead to reduced losses of the electric machine.
    In general, it should be noted that the reluctance rotor may be designed as a toothed rotor or may comprise flux barriers formed by recesses in the ferromagnetic material which form different magnetic resistances for the magnetic flux in the d and q directions. In addition, reluctance runners with {hybrid runners, e.g. she knows of stepper motors) and conceivable without permanent magnets.
    In order to keep the electrical control flow within narrow limits, it can be provided that at least one permanent magnet is provided between two adjacent ferromagnetic stator segments at least partially for the purpose of forming an at least partial flux barrier for the electromagnetic control fluxes. Because of their comparatively low permeability, the permanent magnets arranged in this way conduct the electromagnetic control flow in a flow direction that bypasses them, so that their extent to other stator segments can be restricted. A particularly concentrated control flow can be so for

    Constructive, saturation and assembly simplicity on the stator can be made possible if adjacent stator segments are mechanically connected to one another via at least one saturation web. In addition, such a one-piece stator during assembly of the electrical machine and during maintenance easier to handle, which can be used for a cost reduction.
    If at least part of the permanent magnetic flux closes over the reluctance rotor, over the air gap and over at least one winding-free ferromagnetic tooth of the stator, then the permanent magnetic flux can be kept within narrow extension limits, which can provide for comparatively high flux densities. Therefore, even with permanent magnets having a reduced flux density, a sufficient permanent magnetic flux can be made possible. In addition, a comparatively good stabilization of the passive degrees of freedom of the runner can be made possible by such a flow.
    The same effect on the strength of the permanent magnetic flux circuit may be enabled when at least a part of the permanent magnetic flux via the reluctance rotor, over the air gap and an electromagnetic pole, in particular a tooth, of the stator closes. The permanent magnet flux can thus extend over a comparatively short path over a tooth or pole leg of the electromagnetic pole or in distributed windings of the stator winding within a pole pitch of the coil of the electromagnetic pole, which can provide a compact magnetic circuit with comparatively low magnetic voltage drops. In a simple constructive way so sufficient permanent magnetic flux can be created in order to provide for easy control of the magnetic storage can. It was also found that in cooperation with the

    Reluctance it may be possible that a non-average value, linearly dependent on the stator current waveform over the rotor angle is formed when the stator winding is energized constant. Typical single-phase characteristics with torque fluctuations and starting difficulties can thus be avoided in a structurally simple manner, wherein at high rotational speeds, a simple control scheme for a magnetic bearing or supporting force formation on the electric machine can also be established. Therefore, the invention can not only be distinguished by the fact that a constructive simplicity produces a bearing force direction which is improved in focusing, but also that a new technical effect for controlling the magnetic bearing of the reluctance rotor can be used to simplify the control. The invention can therefore be distinguished from the prior art by robustness, cost-effective manufacturability, as well as by easier controllability of the magnetically mounted reluctance rotor.
    If at least one permanent magnet is arranged in the region of an electromagnetic pole, then a compact design of the stator can be made possible.
    Simple mounting options with respect to the provision of the permanent magnet may result if at least one tooth carries at least one provided in the region of the air gap permanent magnet.
    In order to easily achieve an increase in the flux density, it can further be provided that at least two permanent magnets are provided with opposite polarity.
    If at least one tooth of the stator has at least one recess with an at least partially accommodated permanent magnet, then inter alia the air gap height can be kept small. High flow densities can thus be used, among other things, for improved load-bearing training. For a symmetrical structure, which can be used, inter alia, for a reduction of eddy currents, the permanent magnet can be embedded centrally. It is
    But also conceivable to dig in the permanent magnet or projecting out of the stator in the recess.
    The reluctance rotor can be designed as an external or internal rotor to be used depending on the mechanical requirement for power or torque output can.
    In order to further simplify the design conditions for a cost-effective electric machine, it can be provided that at least one winding of the stator winding is provided on the stator for generating a control flux for a common torque and radial load capacity formation. With a corresponding control can now be set via a winding, the magnetic bearing of the reluctance, as well as its power output. The electrical machine according to the invention can therefore provide over the prior art for particularly compact construction conditions.
    The control conditions of the electric machine can be simplified if the stator winding for the torque and radial load-bearing formation has separately controllable windings.
    If, in the reluctance section, the control and permanent magnet flux essentially run in a common plane, then the design conditions can be further simplified. A cost-effective electric machine can be created, in particular because thus the sheet metal or the laminated core is comparatively easy. In addition, so eddy current losses can be reduced.
    The construction according to the invention can also make it possible for the reluctance rotor to be permanently magnet-free. Thus, inter alia, a low-cost runner can be created, which can be advantageously used for various applications that require interchangeable runners. An inexpensive electric machine can therefore also be made available for such purposes

    become. But it is also conceivable to equip the reluctance rotor with additional permanent magnets, so that, for example, similar to runners in stepper motors biasing the air gap may result.
    If the stator and / or the reluctance rotor have a toothing adjacent to the air gap at least in a partial region, then the electric machine can also be used in a manner similar to a stepping motor.
    Different Polausbildungen in the stator can be made possible by the fact that at least one electromagnetic Polausbildung has at least one at least partially distributed winding.
    Particularly advantageous may be found when provided in a stator permanent magnets in a machine having a three or four-stranded stator winding, in particular tooth coil winding, and a magnetically mounted reluctance rotor, are used to reduce torque fluctuations of the electric machine in which at least one rotor angle in the Essentially formed from the permanent magnet flux of the permanent magnet permanent magnetic circuit is formed, which closes within an electromagnetic, having the same polarity Polausbildung, over the air gap and the reluctance rotor to a magnetic circuit.

    To achieve flux densities, the invention provides that, when the magnetic circuits are viewed separately, a magnetic or electromagnetic circuit 6 within a permanent magnetic pole formation 10 with the same polarity (N), via the reluctance rotor 2 and via the air gap 3 closes. The permanent magnets 7, 8, 7 ', 8' thus segment the stator 2 in stator segments 11, 12, 13 and 14 and force the electromagnetic circuit 6 into a narrow extent, so that compared to the prior art, a comparatively highly focused load capacity {Fi or F2) per segment 11, 12, 13 and 14 can be enabled.
    The adjacent stator segments 11, 12, 13 and 14 may be mechanically connected to each other, for example via saturation webs 31, 32. In Fig. 1, two constructions of saturation webs have been shown. Thus, there is only one saturable web 31 in the permanent magnet 7 ', whereas two saturable webs 31 and 32 have been shown in the permanent magnet 8'.
    2, another embodiment of the electrical machines 15 is shown, for example. Here, the magnetic or permanent magnetic circuit 6 closes within a contiguous ferromagnetic and winding-free sector 16 via the reluctance rotor 2 and the air gap 3. Here, too, an increased magnetic flux density in the air gap 3 can be ensured via simplified design conditions.
    According to Fig. 3, another embodiment of an electric machine 17 is shown. Here, the invention provides that the magnetic or permanent magnetic circuit 9 within an electromagnetic Polausbildung 18 with the same polarity (N) via the reluctance rotor 2 and via the air gap 3 closes. In this case, the pole formation 18 consists of a pole 19 which is formed by a tooth 20 of the stator 4. As can be seen in Fig. 3, the stator has 4 poles 19, 20, 21 and 22, which are each formed by teeth 19 ', 20', 21 'and 22'. However, it is also conceivable that dispenses with a tooth 19 ', 20', 21 'and / or 22' and only the winding 37 of the stator winding 5 as an air coil (or in shape

    In general, it is mentioned that the energization of the stator winding 5 shown in the figures is to be understood as an example. Other forms of the stator winding 5 and their electrical control or energization is conceivable, but not shown.
    3, the permanent magnets 7, 8 and 7 8 'and 7 ", 8" and 7 " 8"' in the region of the electromagnetic poles 19, 20, 21 and 22 are arranged. These are attached to the respective tooth 19 ', 20', 21 'and 22' and protrude into the air gap 3 between the stator 4 and reluctance rotor 2. For improved symmetry are two permanent magnets 7, 8 and 7 ', 8' and 7th ", 8" or 7 '", 8'" on a tooth 19 ', 20', 21 'and 22' are provided, said permanent magnets 7, 8 and 7 ', 8' and 7 ", 8" or 7 '", 8'" have opposite polarity 23, 24, as can be seen for example in the drawn arrows of the magnets 7, 8.
    According to Fig. 5, a further embodiment of an electric machine 25 is shown. In contrast to the electrical machine 17 shown in FIG. 3, this machine 25 shows permanent magnets 7, 8 and 7 ', 8' embedded in the tooth 19 ', 20', 2Γ and 22 ', respectively. This construction makes it possible to provide a comparatively small air gap 3 between stator 4 and reluctance rotor 2. An increased bearing force generation is possible, for example.
    Further embodiments for mounting permanent magnets 7 are shown in FIGS. 9A, 9B and 9C. In Figures 9A and 9C, a permanent magnet 7 is shown buried, and indeed this 7 is inserted into a recess 33 of the stator 4 and fixedly connected to the stator 4. In FIG. 9B, in contrast to FIG. 3, only one permanent magnet 7 is provided on the pole piece of the tooth 19 '.

    According to FIGS. 1 to 4, electrical machines 1, 15, 17 and 25 with a reluctance rotor 2 can be seen as internal rotor 40. However, it is well within the scope of the invention to provide the reluctance rotor 2 as external rotor 41, as has been shown, for example, according to the electric machine 26 of FIG. 7.
    In particular, however, it has been found for the electric machines 17, 25 and 26 according to FIGS. 3, 5 and 7 that, given a constant energization, a force distribution over the rotor angle that is not dependent on the stator current can be achieved, if at least part of the rotor current is generated permanent magnetic flux circuit 9 via the reluctance rotor 2, via the air gap 3 and an electromagnetic pole 19, 20, 21, 22 closes. This is shown in FIG. 8. Here, the novel orbital 27 can be recognized in relation to the known orbital 28. As can be clearly seen, the orbital 27 according to the invention is displaced beyond the tangential force profile 29. With regard to the radial force curve 30 no significant change can be detected.
    This special feature in the load capacity formation is particularly advantageous for low-stranded motors with low number of turns, number of windings or number of coils. The minimum number of windings in bearingless motors is three coils - with star or delta connection four strings, coils or windings. Such constructions are mechanically very simple and inexpensive to manufacture. With the conventional power orbit, such motors have a so-called one-phase characteristic, i. H. There are rotor angle positions in which no torque can be generated. This leads to torque fluctuations during operation or possibly also to start-up difficulties. With the inventive load-bearing orbital, the described one-phase characteristic (in the case of bearing-free motors with four star-connected windings on the stator or on stator coils) no longer occurs. So it can be in each angular position in addition to load forces so generate a torque.
    Another advantage that results is in the method for controlling the electric machine and is for all bearingless reluctance runners (regardless of the

    Number of coils) with shifted load orbit valid. Normally, one needs for the load capacity control the rotor or rotor angle, Under certain circumstances (eg at high rotor speed and / or high damping of rotor vibrations) can now be dispensed according to the invention on a determination of the rotor angle, since for the first time a constant current through a rotor rotation and a For this reason, the method known from magnetic bearings can be used for the first time, even with bearingless motors for the first time.
    Furthermore, distributed windings 34 of a stator winding 5 for electromagnetic pole formation 19 are also conceivable, as can be recognized, for example, in a two-layer coil arrangement according to FIG. Here, the electromagnetic polar formation 19 takes place within the permanent magnetic pole formation 10. With reference to Fig. 10, it will be noted that the circuitry of the coils of the distributed winding 34 has not been shown for the sake of simplicity.
    After the figures 11 and 12, for example, slotless Statorausführungen are shown. According to FIG. 11, a pole formation 19 with a winding 35 made up of air coils is shown. According to FIG. 12, a winding 35 of toriod coils, for example, which also serve to form a pole formation 19, is shown. In the case without a groove, even distributed windings are conceivable.
    In FIG. 13, for example, it is also pointed out, for example, that a winding 37 (in particular a tooth coil winding) can be provided solely for the formation of the load capacity, and a separate winding 38 (in particular a distributed winding) can be provided solely for the torque generation. The two windings 37 and 38 generally have a different number of pole pairs.
    An embodiment similar to the embodiment of FIG. 2 is shown in FIG. 14. Again, a permanent magnetic Polausbildung 16, impressed by permanent magnets 7 and 8, are detected.
